Ohio voters gave Democratic Sen. Hillary Clinton's flagging campaign a crucial win March 4 over Sen. Barack Obama after a tough battle in the delegate-rich state.

"You know what they say," Clinton said. "As Ohio goes, so goes the nation. Well, this nation's coming back and so is this campaign."

Obama appealed most strongly to younger voters, while older voters favored Clinton, according to exit polls.

Republican victor, Sen. John McCain, overwhelmingly won Ohio moderates and conservatives, but he lost the evangelical vote to Huckabee, according to exit polls. Huckabee dropped out of the race after McCain’s victory became clear in both Ohio and Texas.

Eligible voters in both the Democratic and Republican parties will go to the polls on primary day, set for March 4, 2008, and cast ballots in their respective contests. Most of the Democratic delegates will be awarded proportionally based on voting in congressional districts. Most of the Republican delegates will go to the candidate who wins a statewide majority of the votes.
